Title: Three-way valve device
Inventor: FUKUDA RYO
IPC: F16K31/122
Filed: 2000-09-29
Abstract: PROBLEM TO BE SOLVED: To obviate the need of connecting a valve element to a piston, to dispense with a push pin and an O-ring and thereby to eliminate deterioration of sealability of the O-ring. SOLUTION: A valve chamber 11a is separated from a cylinder chamber 12a by a non-magnetic partition 14. A permanent magnet 21 is mounted to the upper end part of the valve element 20 housed in the valve chamber. A permanent magnet 31 is mounted to the lower end part of a piston 30 housed in the cylinder chamber. When the permanent magnets 21 and 31 repel each other and the piston is kept away from the partition by a spring 32, the valve element is separated from a first valve seat 13a by a spring 24 and seated on a second valve seat 14a, so that a first port 13b communicates with a third port 13c.  When air pressure is supplied to the cylinder chamber from an air pressure source 50, the piston is brought close to the partition, and the valve element is separated from the second valve seat and seated on the first valve seat by the repulsion of the magnets, so that the third port communicates with a second port 14b. When the supply of the air pressure is stopped, the first port communicates with the third port.
